Wonderful Wizard of Oz and Zombies

The cyclone didn't just take her house. It took her into hell.
When the storm rips Dorothy Gale from a Kansas farm already haunted by the restless dead, it deposits her in a land far stranger than any fairy tale — a world of emerald spires and golden roads, where the graves have opened and refuse to stay closed.
The Scarecrow hangs half-eaten on his pole. The Tin Man stands frozen mid-swing, rusted and alone. The Lion has spent his whole life running from a war he was always strong enough to win. And somewhere to the west, two witches — sisters, once — have learned to raise the dead and bend them to their will, building armies out of everyone's buried grief.
Dorothy didn't come to Oz to save it.
She came to survive it.
But an axe in the right hands has a way of turning survival into something else entirely — and by the time the Yellow Brick Road is finally behind her, she will have buried tyrants, broken kingdoms, and taught an entire ravaged land exactly what a Kansas farm girl is capable of when the only way home runs straight through the dead.
This is not the story you were told as a child. It is the one nobody dared tell you until now.
A blood-soaked re-imagining of L. Frank Baum's beloved classic for readers who always suspected there was more happening behind that curtain than a kindly old man
